Chesterton ARC 791 Composite
Categories: Other Engineering Material; Polymer

Material Notes: Description: A quartz reinforced composite designed to resurface and restore concrete surfaces, to protect new concrete, and to repair concrete damaged by chemical and physical abuse. ARC 791 has excellent resistance to a broad spectrum of chemicals that are destructive to concrete. ARC 791 is a trowelable overlayment, which can be used at thickness as low as 6 mm (1/4”). ARC 791 is user friendly and will close easily to prevent chemical attack of the substrate by permeation. ARC 791 produces a dense textured surface. Non-shrinking, no solvents, 100% solids.

Benefits:

  • Fine textured, sealed surface produces a tough, durable, chemical resistant, low maintenance overlayment
  • Compatible thermal coefficient of expansion provides long-term resistance to disbondment
  • Moisture insensitive primer provides outstanding adhesion to damp concrete, a unique feature for concrete overlayments
  • User friendly consistency makes installation and finishing fast and easy.
  • The reinforcement is engineered to minimize air entrapment and to improve mixing
  • ARC 791 is stronger than standard concrete and its tough resin structure resists mechanical impact.

Applications: ARC 791 is generally used to repair and upgrade concrete surfaces or used as a replacement for acid resistant tiles, epoxy mortars, fiberglass, and other overlayments. It is formulated to be compatible with concrete. The ARC 791 has the unusual ability to bond to damp surfaces.

Suggested Uses:

  • Acid and Alkali Spill Areas
  • Bottling Lines
  • Equpiment Bedding
  • Pump Bases/Grouting
  • Waste Water Treatment
  • Concrete Tanks/Sumps
  • Food Processing Plants
  • Trenches/Drains
  • Structural Support Columns
